To all whom it may concern:

V SEWALL,

arranged and disposed as to pause therswift instrnmentahties, the

current to pass along the concave bends at. a safe distance therefrom or nearer niiddle-V stream, when the power of the current will soour the bottom of the channel to deepen the same instead of washing ewsy the folio-L elation ofthe banks. t V

A further object is to sever er gnshien the entire slope of the bank along the son'- oeve bends. with a plur ality of pockets or pools of slackened water or eddies caused by e combination of spur-dams and other pockets, pools or eddies While proteeting the bank'from the scouring of the cnr rent, will at the same time cause a, rebuilding of the bank where saving previously prefsiled.

i A still further object of the invention bemg a structure designed to oausetne proper Y accumulation of silt or other sediment ban -dikes or dams ried with the water so that the bank of the stream or river which has the greatest weer thereupon due to the -projection of the stream thereageinst, will be artificially supplemented instead of disgorged,- and by meansof which the rnain. current of the stream is properly diverted to the deep Water. V

A still further object of the present in vention is the provision of a plurality of, that are edapted'to be disst an acute angle to the river bank. those directly in the bend being of length then theones upon either side thereof so that the greatest supplementing er the.

posed barrkwill be at the bend, such dikes or dams 7 being preferably disposed at fiil ElPifiGXi mete angle of 15 degrees to the mhin nintline'of the bank, and projected npstresni.

A still further object of the inrention is the provision of a plurality of sunken reoeptacle dams adapted to he disposed farther out in the stream and to alternate ell} driven 7. tion 'throiigh natural formation of the supplemental sjith thebunk dikes or {131118.81 as to cooperate therewith to assist in the desired supplementing of the bank and at the some time prevent the disgorginfgthereof.

A still Further object of the present invention is the provision of ineans whereby thedikes or dams may be driven or prefersh ly sunken by hydraulicrneans, each d;

orein being composed of plnrslity of seething section of whieh is individuor sunken and eonpled with all sections to form a dike or darn of the desired length. i

' With the foregoing and other ohieets in view which will nppeer as the description proceeds. the invention resides in the cone h instion and arrangement of ssrts nnd in the details of eonstrnetion hereinafter dcsribed and claimed, it being understood that, changes in the precise embodiment of the invention hereindisclosed can be made Within the scope of What IS claimed Without departing from the spirit of the invention.

Th0 main rivl'r hank dikes l and l are ronstrueted in seetions, the main vertieal sertions T themselves being Composed of a plurality' of ITkOIllllti'H adapted to he superposed one above the other, and having attached thereto. strips 8R' the strip 8 ha"- ing (fOIIHH'tQtl thereto, tivo strips 9. \vhioh form a dovetail groove while the strip 3' is provided with tho tongue 10 for interengaging tho groove 9 of the strip 8. These iueinhors T are thus propm'ly soeured together hy means of tho rospeetive strips it and R. and may be driven in position by means of a pile driven but are n'cferably hydraulirally sunken one at a time there l'flillg provided a ehannel 14 through the body of the pilo 7 for the reecption of a hose H. I

In positioning the various piles T in plaro, the ono nearest the hank is primarily positiond being easod down to the mud or bottom of the river Water then being pumpull through the hose Hi the lower end of which is adjacent the lower end of tho piltu and thus displacing the mud or bottom holow tho 0nd of the pile to permit of the easy insertion of the same, all of Whirh is well lmown. The Channel 14 is of sueh a size, as to permit of the introduction of the hose therowithin. and also to permit of the ednction of the Water' due to back flowing while a porpile during the downward sliding movement neoogror ofthe ilejaindefter the lower end of'such, succeeding pile has been; positioned"upon the bottom of the river water is pumped k through the hose H in t e chanhel 1 and:

In order to maintain the proper direction and straight line durin' Q the "dil ting or sinki of the piles, thegon'gitndinsi bracing strips 11' are placed upon either side of driven, and boltedto every third or fourth It is also apparentthet the various driven, elements of the main and auxiliary or Suppleinentingdikes, my be round piling, it being mainly the ,reserrt idea toplace the dikes 1 end 12 at t e angle asillustratedin Fi Irelatively tothe main bank, with the cri eshaped supplemental dihes orfdan s in the position as shown, so'asrto supplement the main dikesl at the extreme bend of the river.

Thus it will be seen that any silt or mud csrried'downstream' will he pocketed upon; both sides of the respective main dikes or dams, and that fiowingoutwardly toward the space between the dikes or dams 3, it will be accumulated with the hrush orotmn' material held in plaoe'by the netting 6, so-

thet the river bank at such point will be supplemented continually due to the precipitation and collection of the silt or mud at such point.

Round piling driven" to a proper depth 3 under certain conditions will not only catch and hold in place the mud. or silt that sloughs from the slope of the river bed hut will also tend to pin the base the slope i of the river bed firmly, so as to prevent any p of the main current.

"By the arrangement as shown in Fig.1, means of which the swift and deeper water will follow the arrows c, it is evident tsined. thus 7 dispensing with eontinual dredging operations to keep the channel the desired depth; and'also the swift water will pass a safe distance irom the lower bank of f the bend B, and therefore not cut away the hank as under normal or natural current flow.

In Figs. 14 and 15, the concrete'piie 24, has: a removable ipe core 25 which is'rnade readily removable after the coalescing of the concrete, by spirally winding rope 26 about the pipe and incasing such coil in paper In this manner, one terminal'of the rope is 1projected exterior-1y of the pile and is pnlle upon to produce a space about the pipe 25 and thereby permit the easy with draws} oi such pipe 25 andto leave a bore through the pile for hydraulic sinking.

7 In all of the piles designed for hydraulic sinking the pipe or hose for furnishing the water may be inserted within the bore to a point adjacent the bottom so that the exhaust may or pipe; or such hose or pipe may be connected in the top end'thewater permitted exhaust'outwerdly irom' the lower end of the ile.

The concrete piles, as shown in Figs. 13.; 1 1 15 may poured or mlh-sd piles and when desired are provided with the metal spiral reinforces 27. V

It is also my intention where necessary and desirable to fill the bores or chsnnels' after the piles are driven or sunken with concrete, which may or may not he reinforced with metal rods.

What is claims/dis:

An apparatus of this character, including a'plurnlity of supplemental bank forming means for rivers and the like, disposed at an acute angle with relation to the bank,

the piles 17 are. to be arranged 1D- olinedlysimilar to the spur-dam 1, or may be positioned at any desiredangle and disto accomplish the result (is.

In 13,h concrete pile 22 havingthe pass up the bore about the hose &

the pocket formed by the acute angle being disposed upstream, and a plurality of angurenting; dikes disposed beyond the bank forming means and alternating therewith.

2. An apparatus fer protection of river hanks ineludin; a plurality' of main dikes extending from the river bank at an acute angle, the outer end of eaeh dike being proieeted upstream, a plurality of supplemental erih dikes disposed to alternate with the hank dikes, and. beyond the outer ends of the hank dikes, eaeh of the latter being V-shaped in top plan with the apiees thereof disposed downstream.

23. An apparatus for protection of river hanks, int-hiding a plurality of nlaintdikes extending from the river bank at an acute angle the outer end of eaeh dike being pr0- je('tld upstream, a plurality of supplemental r erih dikes disposed to alternate With the hank dikes and beyond the outer ends of the hank dikes, each of the latter being V-shaped in top plan with the apices thereof disposed downstr Pain, and a netting secured to the outer edge of each of the V-shaped dikes to assist in holding the collected preeipitate from being carried away by the main stream.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signatllie in the presence of two witnesses.
